Frequent Access Control Systems Troubles We Fix

From untracked keys to outdated door hardware, these are the entry security situations our clients bring to us most.

🔑

Can't Track Who Still Has a Key

Properties that have cycled through multiple tenants, cleaners, or service workers often have an unknown number of key copies in circulation. There is no reliable way to verify a key was returned without physically replacing the lock. We install credential-based systems that make every user individually traceable and revocable without a hardware change.

🚪

Door Frame Not Strong Enough for Electronic Access

Many residential doors are installed with short screws, shallow strike plates, or soft-framing conditions that cannot support an electronic locking unit reliably. A credential system mounted on a weak door frame fails the first time serious force is applied. We assess the full door assembly before installation and reinforce what needs to change before the credential hardware is fitted.

🔓

Standard Lock Picked or Bumped

Standard residential pin tumbler locks are vulnerable to picking and bump key attacks that leave no visible trace on the door. Homeowners often do not realise an entry occurred until something turns up missing. We install high-security cylinders rated against these techniques, combined with access control hardware that eliminates the need for a key entirely.

🏘️

Different Tenants Need Different Access Levels

Properties with main building access, individual unit entry, and shared area access need a system that can enforce different permissions for each person without physical key management. Issuing one key per person creates a management problem that compounds with every new tenancy. We configure independent credential profiles for each user and access zone so permissions are precise and instantly adjustable.

📲

Security Code Shared With Too Many People

A single shared access code behaves like a physical key: once shared, it cannot be selectively revoked. If one person should no longer have access, the entire code must be changed and redistributed. We install systems with individual credentials per user so that revoking one person's access does not require resetting the system for everyone else.

⚠️

Strike Plate Pulled from Frame Under Force

Most residential strike plates are secured with screws no longer than 25mm, anchoring into the door casing rather than the structural frame behind it. Under a single firm kick, the strike plate pulls from the wood and the door swings open regardless of lock quality. We replace or upgrade the strike plate and fastener set as part of every door security upgrade, anchoring directly into the stud framing for genuine resistance.

🔧

Tenant Changed the Lock Without Permission

Tenants who change a lock leave the property owner locked out of their own property and may also void fire code compliance for certain building types. Physical lock changes are difficult to prevent or reverse without direct involvement. We install master-credential systems where the property owner retains permanent override access regardless of what users do with their individual credentials.

🏠

No Way to Give Access Without Being There

Remote property owners and landlords who cannot be physically present to hand over a key lose control every time a new service provider, inspector, or tenant needs entry. Hiding a key creates obvious security risks. We install systems with time-limited remote credential issuance so access can be granted and revoked from anywhere without a physical handover.

📞

Old Intercom System Stopped Working

Wired intercom systems installed in older residential buildings degrade over time, with call stations, wiring, and release mechanisms all failing independently. Repairing individual components of an obsolete system often costs more than replacing it with a current video intercom and access control combination. We assess whether the existing infrastructure is worth maintaining or whether a full replacement delivers better long-term value.

What Our Customers Say

Tomasz W.

No more key headaches with our rental

We have a basement suite that goes through tenants every year and we were constantly worrying about key returns. Ontario Door & Window Pros installed a keypad system and now we just change the code between tenancies. Fast installation, clear explanation, and no issues since.

Aisha R.

Frame reinforcement and keypad in one visit

The technician noticed our door frame was not solid enough for the hardware before he even started. He reinforced the strike plate area and installed the access control system in the same appointment. I appreciated that he flagged it upfront rather than just installing on a weak frame.

Brian C.

Good system, slightly longer than estimated

The wiring in our older home took longer to route cleanly than the technician originally estimated, but he was transparent about it and kept the price consistent with the quote. The keypad and intercom work well and the app is straightforward to use.

Nadia F.

Finally feel like I control who gets in

After two years of handing out keys to cleaners and dog walkers, I could not tell you how many copies were out there. Ontario Door & Window Pros installed a fob system on the front entry and a keypad on the back. Being able to deactivate a fob immediately is a relief.

Kevin L.

Professional work from start to finish

From the site assessment to the final walkthrough, every step was explained clearly. The technician from Ontario Door & Window Pros showed me exactly how to manage credentials before leaving and the whole system has been completely reliable over several months.

Simone D.

Upgraded both the hardware and the lock

I wanted high-security hardware and access control on the same entry. The technician assessed what was there, recommended what needed to change, and completed everything in one visit. The door now feels genuinely secure in a way the old deadbolt never did.
